To elaborate on the reference to L.A.’s aging underground sewer lines etc.: in recent years there’ve been multiple water main breaks causing local flooding in the city and as per news reports aging infrastructure was suspected of being the culprit. ...
Having a house in Huntington Beach, built on sandy soil.. is just waiting for LIQUEFACTION to sink it into the ground.
Quoting: Rayelle  Liquefaction happens where landfill is. Where there is marsh or wetland underneath. Not sandy soil like Huntington Beach. You will have to zoom in on this map, but a large part of Huntington Beach is expected to have a significant amount of liquefaction in a large quake. [ link to maps.conservation.ca.gov (secure)] Cool. Thank you for that. I saw a map of the La Brea area, near the tar pits that have oozed up into the streets. Lots of very small fissure cracks in that area. There is a map showing all the main sewer lines.. many sewer lines are very old original pipes with age or stress cracks in them. When I went to find the CA map of the fault lines that I used to use, it was gone. |
